Iron filings and sulphur powder were mixed together on a clean sheet of paper and mixed together. By using magnet underneath of the sheet observation was taking place. It was observed that only iron filings were easily attached together and moved along with the magnet. By joining together they went spiky and upward. It was seen that under the normal room temperature iron and sulphur didn’t react together, so they where easily separated by using the magnet.

The mixture of iron filings and sulphur powder were poured into the glass test tube, mass 4 (test tube with iron and sulphur mixture before heating) – 27.54 g. It was placed under the Bunsen burner.
